I have messed with this off and on for several years, and this year I used it as my only means of scent control. It definitely still helps several hunts after the initial smoking, but I personally noticed the best results if I re-smoke once a week, or at least every other. I took the buck in my avatar this year, straight down wind, I had smoked my clothes that same morning. It's not a "cure-all" solution, as I do still get picked off by deer occasionally, or often they will know something is up, but not be able to pin-point it. But, I am seeing substantially better results than when I was using manufactured "scent killers" in spray on bottles. You still have to hunt smart, and play the wind. But I firmly believe it can help give you that few extra seconds if they get down wind, to hopefully get a shot off. Btw, I too use a Bee smoker, as opposed to my brother, who just crouches over a small fire. I believe i can get far better coverage with the smoker.
